I dowanna rework the type system. I'm not even 100% sure I want to implement what I actually proposed. I do want to find out if people think the framework makes sense and whether it's the right way forward for those projects that need these features. What you're proposing here sounds suspiciously like something that should be handled by creating domains - but in any case it's almost entirely unrelated to what I was talking about. ...Robert -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
